23 cm. Large-billed vanga. Males have a glossy black cap and dark grey upperparts, with whitish underparts. Dark grey bill. Females and immatures are similar but cap is less extensive, with pale spots over eyes, and paler upperparts. Underparts of juveniles may be washed buffy. Similar spp. From other vangas and Ashy Cuckoo-shrike Coracina cinerea by very deep and powerful dark bill. Voice Calls tseeang very loudly. Hints Found in mixed-species flocks in dense deciduous forest, where it strips bark from dead branches, opens pupal cases and removes epiphytes with its strong bill. The noise of this debris falling aids the location of the species.
